The typical magnification of an ocular lens is 10x. In some microscopes, eyepieces may range from 10x to 25x , with stronger options available in special setups.

Quick Scoop

In most standard compound microscopes, the ocular lens is the eyepiece you look through, and 10x is the common default. The total magnification is found by multiplying the ocular lens magnification by the objective lens magnification, so a 10x eyepiece with a 40x objective gives 400x total magnification.

Typical Range

  • Standard: 10x
  • Common range: 10x to 25x
  • Higher-power options: up to 40x or 50x in some cases
